Msaa-like for sprites

First of all, thank you / congratulation for the amazing job you all are doing with this project !
I have very limited knowledge in 2D/3D games creation, so I may say silly things.

**What problem does this solve or what need does it fill?**

I currently work on a little 2D game with a zoom in/out feature. When I zoom out the sprites start to scale down and became quickly ugly.

**Describe the solution would you like?**

Should it be possible to have something like Msaa for sprites ?
I try to activate current Msaa feature, but seams to only works with 3D.
Could we have some interpolation (linear ? cubic ?) in scale down sprite process ?
